Early aspects: aspect-oriented requirements engineering and architecture design
This paper reports on the third Early Aspects: Aspect-Oriented Requirements Engineering and Architecture Design Workshop, which has been held in Lancaster, UK, on March 21, 2004. The workshop included a presentation session and working sessions in which the particular topics on early aspects were discussed. The primary goal of the workshop was to focus on challenges to defining methodical software development processes for aspects from early on in the software life cycle and explore the potential of proposed methods and techniques to scale up to industrial applications
Economic growth, innovation systems, and institutional change: a trilogy in five parts
Development and growth are products of the interplay and interaction among heterogeneous actors operating in specific institutional settings. There is a much alluded-to, but under-investigated, link between economic growth, innovation systems, and institutions. There is widespread agreement among most economists on the positive reinforcing link between innovation and growth. However, the importance of institutions as catalysts in this link has not been adequately examined. The concept of innovation systems has the potential to fill this gap. But these studies have not conducted in-depth institutional analyses or focussed on institutional transformation processes, thereby failing to link growth theory to the substantive institutional tradition in economics. In this paper we draw attention to the main shortcomings of orthodox and heterodox growth theories, some of which have been addressed by the more descriptive literature on innovation systems. Critical overviews of the literatures on growth and innovation systems are used as a foundation to propose a new perspective on the role of institutions and a framework for conducting institutional analysis using a multi-dimensional typology of institutions. The framework is then applied to cases of Taiwan and South Korea to highlight the instrumental role played by institutions in facilitating and curtailing economic development and growth

Strategies, contributions and inhibitors of information systems to organizational competitiveness: An empirical analysis within the Caribbean
The study examines the impact of Information Systems (IS) through a consideration of improved competitiveness within a multi-business Caribbean firm. The methodology draws on a participant-observer approach for data collection and compares the application of IS by three business units within each of three organizations. It is argued that while there is already a substantial amount of research on IS effectiveness its value in the context of developing countries such as those of the Caribbean will be most significant. In this context firms are perceived to face more constraints than in developed countries so there is a need to explicitly recognize the effects of ‘inhibitors’.
The study finds that for two of these businesses IS can be shown to have contributed to improved competitiveness, while the third had a less satisfactory experience. Analysis of the data revealed that in the two business units where IS contributed the units had been able to improve specific business processes in pursuit of identified competitive strategies. In the unit that did not derive such advantages, limitations in the functionality of the core application combined with insufficient adjustment of business processes, led to the unsatisfactory results. It is also observed that the explanatory value of the empirical analysis is enhanced if we identify inhibitors of IS for competitive advantage and make their effects more explicit
Analyzing impacts of change operations in evolving ontologies
Ontologies evolve over time to adapt to the dynamically changing knowledge in a domain. The evolution includes addition of new entities and modification or deletion of obsolete entities. These changes could have impacts on the remaining entities and dependent systems of the ontology. In this paper, we address the impacts of changes prior to their permanent implementation. To this end, we identify possible structural and semantic impacts and propose a bottom-up change impact analysis method which contains two phases. The first phase focuses on analyzing impacts of atomic change operations and the second phase focuses on analyzing impacts of composite changes which include impact cancellation, balancing and transformation due to implementation of two or more atomic changes. This method provides crucial information on the impacts and could be used for selecting evolution strategies and conducting what-if analysis before evolving the ontologies
An ontology of agile aspect oriented software development
Both agile methods and aspect oriented programming (AOP) have emerged in recent years as new paradigms in software development. Both promise to free the process of building software systems from some of the constraints of more traditional approaches. As a software engineering approach on the one hand, and a software development tool on the other, there is the potential for them to be used in conjunction. However, thus far, there has been little interplay between the two. Nevertheless, there is some evidence that there may be untapped synergies that may be exploited, if the appropriate approach is taken to integrating AOP with agile methods. This paper takes an ontological approach to supporting this integration, proposing ontology enabled development based on an analysis of existing ontologies of aspect oriented programming, a proposed ontology of agile methods, and a derived ontology of agile aspect oriented development
Enhancing skills of critical reflection to evidence learning in professional practice
Professional organisations and regulatory bodies are making critical reflection a mandatory component of professional practice. Reflection is a vital part of learning from experience and is central to developing and maintaining competency across a practitioner's lifetime. This paper will discuss key educational theories to illustrate why reflection is important. Kolb's and Gibbs' reflective cycles are used to structure the process of critical reflection. Elements of the educational tradition of Bildung are discussed and integrated to enrich the understanding of self and to facilitate the reader's ability to enhance their professional practice
